Audiobooks certainly feel like they have much worse retention. To solve this, whenever I listen to an audiobook now, I'll both buy it on Audible and on Kindle. Then, whenever I hear something particularly compelling/important, I quickly hop into the Kindle app on my phone and highlight it. If a book has whispersync[0] enabled this is especially easy. This, combined with having a workflow for consistently reviewing my highlights[1] has improved my (admittedly self-reported) retention significantly. There's plenty of science that supports how effective spaced repetition is for retention.
